WEIGHING-MACHINE.

Specification of Letters Patent.

Application filed June 3b, 1911. Serial No. 636,238.

Be it known that I, S'rsrnnx. \Yns'r GROOMIE, a subject of theiliing of Great Britain and Ireland, residingwat \Vortley, Leeds, in the county of Yorke "ire, England,

machine or appliance comprises'a frame or a 1i ing jack connected to said supportand and a pressure indicatorconnected to said jack.

' he frame or support can be made of any suitable shape or design and is providedtion for the lever. One end of the frame or, support is adapted to bear against the rail on which a locomotive or the like is standing, and a suitable clip or clips is or are provided for keeping the frame or The 0 her end of the frame or support is connected with the lifting jack. This endof. the frame or support is also furnished with adjustable foot screws for frame or. support.

A suitableqveighing lever is mounted on the bearings'i n the frame or support, one'end with some part of the wheel (if a locomotive or the like, preferably with the bottom portion of the wheel tire that projects beyond the rail head. The other end of the lever or pressure -cylinder.

In connection with the liftin g'jack is an jack may consist of a small .piston working 1n a cylinder incommunication with the ressure side of the jack ram, the piston ing controlled by a spring or springs and pliance according to this invention.

,Figures 1 and 2 of the accompanying illustrative drawings show in side elevation and plan respectively a weighing machine or apis a detail view.

In the COIIStIIICQ QQ showni the frame or support, 1s constituted by two membersa arranged'side by side and held thedesired distance apart by distancepieces I) and a--' channel shaped holder c-,'"bolts d securing the members.- together and to the hold er;

At one end the members a are adaptedil'to abut against the rail e of arailway and rest upon theflower head or flangeofsuch rails asshown. At the otherend the'niembers (z are eachvbentoutwardlyand fittedwith a screw foot f bytmanipulationofwhich the level of the frame or ,supporlncan ad Fulcrum blocks 9, .Fig. 3, are adju stably secured to the frame .or support by set screws k that pass through slots formed therefor in the-holder c and members a,

the weight on the fulcrum blocks being taken 1 by the frame or support through packing pieces m inserted between the outwardly extending upper end of eachifulcrum block and the corresponding member, a and side of the holder 0. \Vorking in the fulcrum blocks g is a knife edge bearing 11 fixed in a fitted weighing lever 0 that extends; parallel to the 'members a and one end of zwhich is with a knife edge or nose of tool steel adapted to bear on that portion of the bot)- tom. of a wheel'ti're r that projects outwardly beyond the rail e. The other end of the lever o is fittedwith a bearing block 8 adapted to be engaged by a knife edge It mounted on the outer end of the ram '14 of a hydraulic jack the cylinder. w'of which is connected to the members a of the frame or support .by pivoted tension rods 42:. -The upper end of the cylinder 41: is furnished with a gage y ada'ptedto indicate the pres sure per square inch'on the ram '14: and the corresponding weight in tons and cwts. on

the distant end of thelever 0. Y

For. the-purpose of holding the frame or support up to the rail e there is arranged at each side ottheframe or support a clipbar 1 the outer end '2 of which is hooked to engage the lower head or flange of the rail e and the inner end of which is slotted to engage the corresponding arm of a T- shaped'tie plate 3 that is drawninwardly in order to cause the rail e to be firmly gripped between the members a and the hooked ends 2 of the clip bars, by a cotter that extends through slots in the members *0, and engages the hooked end 5 of the third arm of the tie plate 3.

To ascertain the weight on'a locomotive axle for example, the frame or support is placed in position at rightangles' to the rail e, as shown, with the nose end .of the lever o engaging the underside of the projecting portion of the wheel tire r, or any other suitable part of the wheel. The jack, or pressure cylinder w is arranged in the position shown and pressure is applied to the ram'u to force the long end of the lever o downwardly and lift the wheel clear of the rail e, the weight on the wheel being registered on the dial of the indicator-y.

' In order to ascertainthe pressure or'load ""on the axle or springs of a locomotive,
